IMPROVEMENT IN NUT-CRACKERS.

The Schedule referred to in these Letters Patent and making of the same.

I, JOSHUA Poser, of Philadelphia, in the county of Philadelphia and State ot' Pennsylvania, have invented certain Improvements in Nut-Crackers, of which the followingis a specification.

My invention relates to a peculiar construction and combination of simple devices, by means of' 'which suiicient strength and power combine with comparatively little weight, dimensions, and cost, to crack nuts of diierent sizes and degrees of hardness, in or-4 der that the kernels may be extracted therefrom.

Figure l is aside elevation of my nut-cracker, the opposite side, not shown, being its duplicate or counterpart, with a portion of' the lever L broken off.

Figure 2 a View of' the lever L in fig. 1, detached and turned on its side. i Figure 3 represents a modification of the slot S in A fixed jaw, J, toothed or corrugated, is formed by a prolongation from .the rib or support D, both resting on a broader' base, B.

D projects up and over J, terminating in a head, H,

'which is provided with a rounded flange, F, and its counterpart, running partially aroundthe same, and whose inner sides oredges ibrmbearings for correspending circular parts O C of a bifurcatcd lever, L, iig. A2.

vA stem or upright, R, terminating in a toothed jaw, Ji, is cast within the head H, to be movable therein according to a method known to those skilled in molding and founding.

J and J are at'au angle with each other, the point of their greatest divergence being at or near the junction4 of the stem R and the jaw J.

The object and advantage of this arrangement consists in allowing the larger and harder nuts, especially the common black walnut N to hc received nearest the line of direct pressure.

The jaw J' is actuated in a vertical direction by means of short pins P P, iig. 2, cast eccentrically on the circular parts CU ot' the lever L, working into their duplicates, in flanges or olf-sets K and W, stauding out from D.

It is moved, so that S and Z are brought iu line, or coincident with each other.

The pins P P slide into the slot S, and its opposite, until the rounded parts C C of the lever bear against the corresponding rounded parts of the flanges-F.

L is now lifted up, and, in consequence of the pins being placed eccentrically, it is clear that R, and, consequently, J are elevated.

It is also plain that, owing to the flange W, the said pins are prevented from slipping out from the slots S, except at one point; that is, when Z and S are in line with each other. Y g

L is secured in proper position by means of a spring attached for the purpose, lapplied in the manner shown in the drawing, or otherwise, as may be preferable.

A spiral spring, V, catches around the hook A, and is bent around through the opening O inthe lever, provided for the purpose.

If, now, the nut N is inserted between the jaws J and J', it is cracked open immediately upon the forcible depression ot' the lever.

The slot S may pass entirely through from side to side of R, as appears in iig. 3, and a pin inserted eccentrically through the circular-parts C C ot' the lever, and through'the slot S.

This n'iodiiieation, however, would necessitate drilling and riveting, both ot' which are avoided by the plan rst described.

Claims.

l. The combination of the jaws J J', thc slots S, the flanges or bearings F, andthe lever L, provided with the rounded parts C and the pins P, as and for the purpose speced.

2. ln combination with the foregoing, theV slotsX and Z, as specified.

3. lhe stem R, in combination with the jaw J,

working within the head H, substaptially as hereinbefore described and specified.
